Glow in the Dark Dumpling Squishy, Mystery Box

Every box leaves the factory sealed. Nobody knows which one is inside, not us, not you, not the person you hand it to. Twelve glow designs to hunt: six shot through with glitter that catches the light, six in solid colours. All twelve keep shining once the room goes dark.

Press one flat with both thumbs, watch it fill back out, then turn the lamp off and see where it went. One blind box, one glow dumpling, zero spoilers.
